To all whom it may concern:

into Tractors, of which the following is a specification.

My invention relates to tractors and more particularly to attachments to vehicles, and the object is to provide tractorswhich may be attached to vehicles and particularly to motor propelled vehicles, to provide trac tors which can be used to draw plows, harrows, cultivator-S, mowers, reapers, and other agricultural implements.

One object is to provide a tractor which can be quickly attached to or detached from any ordinary vehicle, and which may be conveniently attached by removing the rear wheels of the vehicle and putting tractor drive wheels in their places and then supporting the rear part of the vehicle on the tractor frame.

Another object and advantage is to provide tractor'attachments which will leave all parts of the power plant of the motor vehicle and all bearings in their normal po sitions so'that there will be no disturbance of the working parts and no disturbance of the lubricating systems of the running gear.

Other objects'and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a side elevation of a motor vehicle with a tractor attached thereto, with the rear wheels of the vehicle removed and wheels have, thus making feasible and practlcal to change the wheels on the vehicle whenever desirable: The vehicle can thus be used for transportation purposes or for power purposes. A person can ride to his field in his vehicle, take ofi the rear wheels of the vehicle, and then attach the tractor and be ready for plowing or other work. When he quits work, he can detach the tractor and put on the vehicle wheels for traveling. The rear axle 2 of the vehicle is supported on the tractor beams 3 which are connected to the axle 2 by U-bolts 4 and the beams 3 may be either above or below the axle 2. The beams 3 are extended to the front part of the vehicle on top or bottom of the front axle 5 and attached thereto by U-bolts 6. The rear ends of the beams 3 are supported on the axle 7 which is provided with traction wheels 8. The axle 7 and the beams 3 and the tractor wheels are so positioned relative to the body of the vehicle that the body of the vehicle and the running gear thereof will operate in their normal positions. The wheels 7 can be made larger or smaller in diameter. It will be seen that the wheels .7 can be large enough in diameteitto permit the beams 3 to be placed on top of the axle 2 and under the axle 5 without disturbing the normal position of the bodywand runing gear of the vehicle.

The wheels 1 drive sprocket chains 9 and the chains 9 drivesprocket wheels 10'which. are loosely mounted on a counter shaft 11 which is mounted on beams 3 and connected therewith by U- bolts 12. The wheels 1 are driven by the differential gearing of the vehicle. Sprocket wheels 13 are rigid with the sprocket wheels 10 and are driven thereby. The sprocket wheels 13 drive sprocket chains 14 and these chains'drive sprocket wheels 15 which are rigid with the main supporting wheels 8. Thus the traction wheels 8 are driven from the vehicle gearing which is driven by the power plant of the vehicle. The vehicle driving gear is not de scribed or illustrated in detail because no claim is made for the vehicle driving gear, and this gearing need be shown only in conventional form. The gear ratio can be varied or changed for suitable speed and power. The gearing illustrated shows a re duction of speed and a gain in power. The arrangement of the sprocket wheels 13 rigid with the wheels 10 and loose on the shaft 11 and the gear wheels '15 rigidwith thewheels' 8 and loose on the shaft *7 conserve the advantage gained by-the differentialge'aring of the. vehicle. IA yoke is p1v-- otally connected to beams 3 by clips v l e an adjustable weight'mofunted on saidfbeams fordraw'ing plows(in-implements. 1 a A water tank is carried on the. tractor frame and held in place thereon by braces 17 which are attached to the {beams 3 and to. the 'tank and-by foot braces 18 which are attached to the frame beams A hose I9 is connected to the bottomgof thetank. .16 and 'extendediorward and'conne'cted by a coupling 20 to the hose 21 which con.

nects the radiator 22 with the pump 7 pendently-of each other, a water tank mounted'o'n said beams over s'aidIsup'porting axle,

The'hose, 21 is provided with a three wity cock 24: so that the water from the radlator 22- can be cut-oil and ,thewater from-the 5 hose 19 connected inthe hose 21 and sent to 20' the pump-23 which delivers-the water to the jackets of the cylinders in the casings 25.: 'A dhose 26 is connected to the upper part. of v the tank 16. and extended forward and c0n- ,nectedtothe hose 27 which is connected to the upper part of radiator 22 and to the .upper parts of theijackets ofthe cyl nder casings 25. .The pipe- 27. l S p IOVilded Wlth a three-way cock 28 for the purpose oftur'ning the water. from the radiator 22 and direct- ,ing the same through the hose E26 to the. tank I 16. The "hose 26 is :connected to the hose 27 by-a coupling 29. ,The couplings 20 and I 7 2 8 and the three-way cocks 24; and 29 ythusprovide means' by which the waterm'av be used either from-the radiator 22 -01 from j I p v traction heels loosely engaglng said sup; 16 provides the necessarythe I tank' 16.

The water tank increased quantity 'ofwater for cooling the engine. This is-necess ary in theconstant slowmovement of the vehicleqwhen plow ing or-domgother work. In slow movement there may not be suflicient 'cooling of V the radiator by airQ, The large tankmakes feasible and practical the necessary gvaria-f f tion of the weight on the traction wheels. 3 For s ome'plows a fixed weight will be-n'eces-..

'. quire a greater weight. The weight can bean automobile .or amotor propelled vehicle of sary and other plowsor implements will revaried as desired by the amount of-water placed in the tank 16: 'Thetank' is thus 4 ma do to perform a double function.

By means of the provision hereinset forth,

\ ordinary construction'can bereadily converted into a tractor-for drawing p 10ws. or r other agricultural implements without dis- F turbmg the working parts or running gear ofthe vehicle and without changing posi tion of the body-and the lubricating systems,-

the body remaining in its normal position which is' usually horizontal.
